Flat Spelt

#a57f1a
Notes

Flat Spelt (#A57F1A) is a true amber with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (44°, 73%, 37%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Flat
adjective

Old Norse flatr, flat / level. As a color modifier, flat implies a clear-and-evenly-spread quality where the hue carries the matte-finish visual register of unmodulated single-plane surface. Sits at the crisp-and-balanced end of the grid, parallel to level and even in usage.

Spelt
noun

Triticum spelta, the ancient wheat species cultivated in Europe since the Bronze Age — slowly returning to artisan baking after a century of displacement by modern wheat. The color refers to a fresh-baked spelt loaf: a soft, slightly muted warm tan with the slightly nuttier finish of ancient-grain flour.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
